Valve selection

[hyhammer]

Can someone help me please. I have to select a hydraulic valve for switching of the pressure line (please take a look an attached picture). Max. flow is Q=215 l/min, Max. pressure is 185 bar. I need an information which of the hydraulic valve is the best for my case but from Bosch-Rexroth or Parker. Thank you very much for answer.

Why Parker or Bosch are not fit for service, or they are, is not possible to conclude from your post. I think you need to submit much more details, as well as why you are looking for alternative solution.

You're right. I didn't have enough time so I have expected at least the category of the Hy-valve.
Hydraulic valve should have:
- 4 main ports
- Spool symbol you can see from the picture
- With spring return
- DC voltage 24 V
- Electrical connection: Individual connection without mating connector with connector DIN EN 175301-803
- Seal material: FKM seals
- and should be from Bosch-Rexroth or Parker

Qmax=215 l/min
pmax=185 bar

Thank you for answer.

It seems there are a few models from the Parker catalog which apparently fit your requirements:

(the document is 29MB size so be patient with page loading).

Rexroth catalog can be accessed here:

I saw just now that they offer CHoose software for configuring Hydraulic assembly (see:

I have already selected the hydraulic valve.

Thank you anyway.
